Re: [hreg] Solar, wind and rainwater for a school
May be Jack, a TCEQ Level III Certified Water Specialist and founding father of ARCSA the American Rainwater Catchment Society of America, could visit Aden, Yemen and gain some experience how the people built rain catchments over 2000 years ago. The Yemeni government is now in the process of restoring those rain water catchments. Due to modernization of the city of Aden, water has become a major commodity. They are resorting to the art of their ancestors that built a great civilization over the past three millenia. Some of the photos shown below reveal how they built catchments, water dams, and high rise buildings centuries ago.
The city of Aden is built at the base of an ancient dormant volcano. It is like a funnel During the heavy rain season. the water would drain to the center where the ancient Yemenis built rain catchments with multi levels. When one got filled it spilled water into the next one and so on. Any extra water was diverted through canals miles away to irrigate farms. When you visit the site you marvel how they did it nearly 2500 years ago. About 200 miles away is the city of Ma'arib - the ancient city where Queen of Sheba had her ancient palace & temple built. Contrary to the Biblical views, Queen of Sheba is not from Ethiopia; she was from Yemen. Over the past three decades the archeological digs have uncovered the tenple of the sun & her palace. The ancient dam of Ma'arib collapsed around 300 AD and drowned much of the people living downstream. This story is told in the holy book of Islam - the Qur'an. Many sections of the dam is still in place. It is another marvel of engineering that Yemenis built around 700BC. They captured all the rain water between a series of mountains; they built the dam with many gates that diverted the water to low lands around Ma'arib for agriculture. I have seen the remnants of some of these canals that supplied water to farmers miles away even months after the rain season had ended. Yemen is a very interesting country.
Watch the scenic pictures of Yemen. Many of these cities are on UNESCO's list to preserve the anciet art and history.

Yemenis built these high rise buildings while Europe was still in the medieval period

The school got the grant but then was delayed by hurricane Ike and now work has begun. If you would like to help, please let me know. I'm especially looking for someone who knows about or wants to learn more about rainwater catchment systems.
